Almond {51111312}

Shared Reference Notes

• [1.1] 
  - Almonds > increased relative abundances of Roseburia, Clostridium, Dialister, and Lachnospira
• [1.2] 
  - There were no significant differences in abundance of fecal bifidobacteria following consumption of whole almonds, ground almonds or control . - Consumption of almonds (whole and ground pooled) resulted in higher #Butyrate (24.1 μmol/g) in comparison to control (18.2 μmol/g. - There was no effect of almonds on gut microbiota at the phylum level or diversity, gut transit time, stool consistency or gut symptoms.
• [1.3] 
  - Almond consumption increased the relative abundances of Lachnospira, Roseburia, and Dialister. - chopped almonds increased Lachnospira, Roseburia, and Oscillospira. - while whole almonds increased Dialister compared to control. - microbial fermentation of finely ground almonds has been shown to increase #Butyrate concentrations
• [1.4] 
  - #2-methylbutyric acid is produced by bacteria when carbohydrates are limited, indicating a transfer from saccharolytic to proteolytic metabolism potentially due to increased availability of almond proteins.
• - consumption of whole or ground almonds for 4 wk had no impact on fecal #Bifidobacteria numbers; indeed, the abundance was numerically lower in the almond groups.
• [#Short Chain Fatty Acid] - ignificant increases in the SCFA #Butyrate and several VOCs after almond consumption
• [1.5] [#Urolithin A] [#Walnut] 
  - UA is a bacterial metabolite produced by dietary #Ellagitannins and #Ellagic acid. - These #Polyphenols are found in plant products, mainly in pomegranates, berries, walnuts, and almonds, but also in some tropical fruits, medicinal plants, and herbal teas - UA is involved in mitochondrial health, and its anti-inflammatory, anti-oxidant, and anti-apoptotic properties. - the formation of urolithins declines with age.
• [1.6] 
  - almonds (dose of 42 g/day) > increase in the relative amount of #Lachnospira, #Roseburia, and #Dialister
